JOHN W. COSGROVE, 0F MEDEORD, MASSACHUSETTS, ASSIGNOR TO UNITED'SHOE 1 MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that I,J0HN W. Coscnovn, a

citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Inserting Fastenings, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings-indicating like parts in the several figures.

- This invention relates to machines-for inserting fastenings and more particularly to fastening inserting machines for use in the manufacture of boots and shoes.

The invention is herein illustrated as embodied in a'machine especially designed to insert staples of fine wire throughthe upper and channel lip or rib of a sole and to clench the staples upon the lip or rib to constitute permanent shoe fastenings.

An essential element of a machine for inserting such staples is the means for clenching the projecting .ends of the'staples since the precision and certainty with which the clenching is efiected depends to alarge extent upon the holding power and etliciency of the staples. In the use of machines of this type upon shoes in which the staples are clenched in a channel provided in "the sole, considerable ditliculty is experienced both in positioning the clenching anvil in the channel to eflect a proper clenching of the staples and also in feeding the shoe along in pro-- gressive stages to locate successive fastenings.

One of the objects of the present invention, therefore, is to provide improved clenching means which will be especially adapted to operate in a channel in the sole.

T 0 this end the invention aims to provide a clenching anvil comprising means for clenching the projecting ends of the staple and means adapted to enter the channel and open it up in advance of the clenching means, thereby facilitating the accurate clenching of the staples in the channel and at the same time facilitating the feeding of the shoe into the different staple receiving positions.

Other objects and features of the invention will appear from the following description when considered in connection with the MACHINE FOR INSERTING FASTENINGS.

accompanying drawings and will then be polnted out in the claims.

In the drawings z- Figure 1 is a perspective View of a clench to which reference may be had for a full description of its construction and operation.

It will be understood however, that the in vention'is not restricted to use in machines of the type shown in said Letters Patent. The machine of said Letters Patent comprises, briefly, a staple forming mechanism, a staple driving mechanism arranged to insert a staple through the upper and channel lip or rib of the insole and a clenching anvil which cooperates with a throat to press together theparts through which the staples are inserted and to clench the projecting ends of the staples which, in a shoe of the type having a channel in the sole for the reception of the inseam stitches, are located in the channel. In accordance with the present invention, the clenching anvil 2, the

general construction of which is the same as that shown in the above mentioned patent, has a relatively thick channel entering nose comprising a substantially vertical channel lip engaging face 3 having a staple clenching cavity 5 formed therein near one side of the nose in the line of staple drive, the leading part 6 of the nose 3 being laterally extended from the clenching cavity 5 and tapering gradually from said clenching cavity to its leadingedge to open the channel and turn up the channel lip against the cavity in the nose upon shoe feeding movement relatively to the anvil 2. It will be observed that the anvil nose has its upper face 8 inclined upwardly and backwardly over the clenching cavity 5, the construction being such that the plow-shaped part 6 and the surface 8 progressively turn up the channel lip and open the channel in advance of the clenching cavity 5 upon shoe feeding movement relatively to the anvil. The ver tical face 3 of the anvil preferably intersects the bottom face 9 of the anvil throughout its length so that it forms a comparatively long sharp edge whereby the anvil may be forced down into the bottom of the channel as shown in Fig. 3 and also offers a substantial bearing against which the shoe may be held during the fastening inserting oper ation.

In presenting a shoe to the machine to receive a fastening the plow-shaped portion 6 of the anvil readily enters the channel in the sole and opens it up sufliciently to enable the anvil to be positioned in the channel so that it may cooperate with the throat 12, Fig. 3, in pressing together the parts of the upper through which a staple is to be inserted and to insure the position of the clenching cavity in line with the plane in which the staple is driven. As the shoe is moved relatively to the anvil into position to receive other fastenings the plow-shaped nose of the anvil readily forces its way along the channel and the inclined face 8 engages the channel lip 13 and turns it up, as shown in Fig. 2, out of the way of the staple clenching cavity so that there is no danger-of its becoming caught between the clenching cavity and a staple as often happens with the clenching anvil now in use. It will be noted that a particular advantage obtained by the use. of the clenching anvil above described is that the shoe may be moved along in progressive stages with the anvil always in position in the channel and the channel opened up to receive the clenching cavity while with the anvils heretofore used, the channel had to be opened upv and the anvil positioned for each staple inserting operation.

Having described my invention, I claim as new and desire to secure by Letters Patent of the United States 1. In a machine for inserting fastenings, an anvil for clenching staples inserted through the upper and channel lip of a shoe, comprising a relatively thick channel entering nose having a staple clenching cavity formed therein in the line of staple drive, the leading part of said nose being laterally extended from the clenching cavity and tapering gradually from said clenching cavity to its leading edge to open the channel and turn up the channel lip against the clenching cavity in thenose upon shoe feeding movement relatively to the anvil.

2. In a machine for inserting fastenings, an anvil for clenching fastenings inserted through the upper and channel lip of a shoe, comprising a relatively thick; nose formed to present a channel lip engaging face having a clenching cavity formed therein in the line of fastening drive, and a channel opening plow offset laterally fron said nose in position to turn up successive portions of the channel lipj to open the channel in advance of the nose.

5. In a machine for inserting fastenings, an anvil for clenching staples inserted through the upper and channel lip of a shoe, comprising a relatively long nose shaped and arranged to; enter the channel and to present a substantially verticalchannel lip engaging face 3 having a staple clenching cavity 5, formed therein nearone side of said nose, and at the other side of said nose having its upper face 8 inclined upwardly and backw-ardly over the clenching cavity to form a; plow- 6, 8 for progressively turning up the channel lip, and opening the channel in advance of the clenching cavity upon shoe feedi g ovem nt e a i y to the an In testimony whereof I have signed my name to this specification.
